TBANSBIISSION-GEARIN.

Application filed October 8, 1910. Serial No. 585,916. Renewed September 20, 1912.

T 0 all 'ui/mm it may concern.

Be it knowi'i that I, CLARK XV. Pannen, a

pitizen of the United States of America, and' `My invention relates to improvements 'in -transmission gearing, and particularly to the class of transmission gearingY of the type employed for transmitting driving move-v ments at. variable speeds and in diiferent di- IGCiiOns from the driving to the driven eletudinallyinto ments of motor vehicles, machine tools, and other mechanism.

My invention relates specifically to that type of 'transmission gearing of this character in which positive jaw clutches are Verriployed for bringing about-,the changes of driving relation as distinguished from that type in which the gear wheels slide longiand out of mesh with each Other as is Very commonly'. in use at the present day, the former having great advanv tagesin strength and positiveness of operation over the latte-r style.

The main objects of my invention are, first, to reduce the size. of the gearing as a Whole, and particularly to reduce the length of the sliafts employed when con- Asidered in relation to the number of such shafts and whilearranging for four different driving rela-tions; second. to provide such interlocking mechanism as will cause all of the clutch means not being operated at any one time to be locked during the time the other clutch mechanism is. being operated; third, to impro-ve and simplify the clutch operating means; and fourth, to im prove generally Vthe form and construction of the parts and the means by which they are operated, all as will appear more fully hereinafter.

To ,the foregoing endsI my invention con sists in many novel details of construction and combinations of parts such as will be fully pointed out in the `following specilicw Specification of Letters Patent.

ition, and iii order that my invention may be thoroughly understood, I will now proiiig reference to thel accompanying draws Central vertical longitudinal section through a' transmission gearing constructed in accordance with my invention. Fig. 2 is a vieu' in horizontal section thereof upon the plane of the line 2-2 of Fig. 1. Fig. is a transverse sectional View thereof upon the plane of the line 3-3 of Fig.v 1.

Fig. 7 is a detail View in longitudinal vertical section upon the line 7--7 of Fig. Fig. Sis a view indevelopment of the transmission gearing generally, the several shafts being swung around into a View the relationship of the various gear wheels with respect to each other.

The driving and driven shafts arranged longitudinally in line with each other is common, both of the said shafts being journaled in suitable bearings ina casing 12, the driven shaft 1l being pro-v vided in addition, at the forward end thereof, with a bearing 13 carried' at the adjacent rearward end of the driving shaft 10 (see particularly Fig. l), Mounted parallel lt'and 15, the former of which l term vherein vthe intermediate shaft,7 and the latter, the reversing shaft. These two shafts are likewise journaled -in suitable bearings in the casing l2, and lines Connect-ing their axes form a triangle as will be readily understood by reference the transverse Seotional views of Figs. 3 and 4. fast. upon the drive shaft is a pinion 16, the teeth of which are in mesh Withthe teeth of a spur gear 17 mounted fast upon the intermediate vshaft 14. Secured fast to reed to describe an embodiment thereof hay- In the drawings: Figure l is a view ir. I

with the Shafts 10 and ll'are two other shafts l i Mounted i mentioned gear wheels aire secured fast upon their res ective Shaftsv it follows that thedrive sha t, the intermediate shaft, vand the reversin sha'ftwill rotate constantly, the interme iate shaft at a lower rate of speed and in'a reverse direction to that of the drive shaft, andthe reversing shaft at a still lower rate of speed but in rection as-that of the drive shaft.

In addition to the above mentioned gear Wheels the following gear wheels are mount- Upon the dri-ven shaft there are two gear h wheels '-2'1. These two gear wheels are secured' fast together but they rotate freely *upon the driven shaft 11. The teeth of these gears are disposed in mesh with the teeth of complementary gear wheels 22-23 A,loosely and independently mounted upon the intermediate shaft 14. The teeth of the gear Wheel 21 are also arranged in mesh with a complementary gear Wheel 24 loosely mounted upon Athe reversing shaft 15. The various loosely mounted ge'ar Wheels are arranged to be connected with their respective shafts by' suitable clutch mechanism, and a 'clutch mechanism is also provided for connecting the driving and driven shafts directly together, all of which I will now describe. v Mounted insliding relation upon the `driven shaft 11, but connected to rotate therewith, is a collar 25 carrying two jawl clutch elements 2,6-27. The jaw clutch element 26. is arranged to coengage with teeth or jaws 28 upon the gear wheel 16, While Ithe lclutch element 2'( is arranged for coengagement with teeth or jaws 29 upon the lgear wheel 20. 'When the collar is mo'ved to the left (as viewedin Figs. 1 and 8) the clutch element 26 will co-engage withv fthe teeth or.jaws' 28, .and so by connecting the gear Wheel 16 upon the shaft 10 with the shaft 11, will directly .connect the driv ing and driven shafts together. If, on the other hand. thecollar 25 be shifted to the direction.

right-(as viewed in Figs. `1 and 8) then the gear wheel 20 will be connected with Vthe driven shaft 11. In order -that driving movements be imparted, however, to either of the gear `Wheels 20-21, it will necesv Asary to connect either one of the gear wheels 22 or 23 with the intermediate shaft 14, the

latter it will be remembered constantly r0- ta-ting by reason of its connection through the -gear Wheels 16 andl' With the drive shaft. Either of 'these gear wheels may be' connected with the shaft 14:l by sliding them vlongitudinally upon the shaft in the proper The gear whe/el 22 must be moved the same dito the right (as viewed in Fig. 8), the effect whereof :will be to cause the co-engagement of jaw clutch teeth 30 carried by the said gear wheel 22 with complementary jaw Aclutch teeth V31 carried by the shaft 14.

and. 23 to effect the foregoing result while ed loosely upon their Arespective shafts.

retaining a proper in'termeshing relation between the gear wheels 20-22 and 21-23. lt will also be noticed that, as the ratios of the gear wheels 20- -22 and 21*23 differ, there will be a different speed ratio and hence a different rate of speed at which the driven shaft is driven with respect to the drive shaft in accordance with the set of gears through which the driving movements are imparted. For instance, if the driving movement-s are imparted through the gear wheel V22 to the gear wheel 20 a greater rate of speed will result than if the driving movements were imparted through the gear wheels 23 and 2l. 4From the foregoing it will be apparent that the highest forward speed, z'. e., direct drive, will result from the movement of thc collar 25 to the left, as lviewedain Fig. 8, While the gear wheels 2.2 23 are maintained in their normal idle positions; that 'an intermcdiate'r'ate of speed will result if the collar 25 be moved to the right,A as viewed in Fig. 8, `simultaneously with the movement of the gear wheel 22 to the right., while the lowest rate of speed will result Vif the gear wheel 23 is moved to lthe left, as viewed in Fig. 8, while the collar 25 is moved to the right, the gear wheel 22 remaining off course in its neutral inoperative position at such time.

To effect reverse driving movements it is necessaryto connect the gear wheel 24 with the reversing shaft 15 While retaining the gear wheels 22-23 in their neutral inoperative positions upon the intermediate shaft 14 and moving the collar 25 upon the driven shaft over to the right. Driving connection will then be as follows :-from the pinion 16 upon the drive shaft 10 to th-spur gear 17 upon the intermediate shaft, f thence through the pinion 18 to the spur gear 19 upon the intermediate shaft, thence through the gear wheel 24 upon the reversing shaft to the gear Wheel 21 upon the driven shaft. It' will be noted that in Fig. 8 the gear wheel 24 is not shown in engagement withy theA gear wheel 21,.but this is because in the development the shaft 15 is swungaround from lts'proper position ywith, respegtto-the ruines@ teeth 34- eonstitutifuer one elena-iii' d clutch, the other element rompi* iii-iV plementary teeth earl-led liv ilie sai; no i Wheel 24.
